1 INTRODUCTION

Roseburg Forest Products (RFP) owns and operates a medium-density fiberboard (MDF) manufacturing facility located at 2685 North Pacific Highway in Medford, Oregon (the “facility”). The facility currently operates under Title V Operating Permit No. 15-0073-TV-01 (existing permit) issued by the Oregon Department of Environmental Quality (DEQ) on June 8, 2017.

Maul Foster & Alongi, Inc. (MFA) has been retained by RFP to assist the facility with the dispersion modeling and risk assessment component of the Cleaner Air Oregon (CAO) permitting process. On May 30, 2019, RFP submitted the toxic air contaminant (TAC) emissions inventory to the DEQ for review and approval to satisfy the initial step of the CAO permit application process as specified in Oregon Administrative Rule (OAR) 340-245-0040(3). The DEQ completed internal review and approved the submitted TAC emissions inventory by letter dated January 8, 2020.

As stated in OAR 340-245-0030(2)(b), a modeling protocol must be submitted no later than 30 days after receiving DEQ approval of the emission inventory. RFP intends to conduct a Level 3 Risk Assessment to estimate the potential excess cancer risk and chronic and acute noncancer risk (expressed numerically as the chronic and acute hazard index) impacts from the facility for comparison to the applicable risk action levels shown in OAR 340-245-8010 Table 1. The remainder of this modeling protocol outlines the proposed modeling methodology and specific information required by OAR 340-245-0210(1).

2 FACILITY DESCRIPTION

2.1 Facility Location

The facility is located in Medford, Oregon, within the Medford urban growth boundary. An aerial image of the facility location and the property boundary is shown in Figure 2-1. The northeastern and southwestern property boundaries are adjacent to Oregon Highway 99 and the Central Oregon & Pacific Railroad line, respectively.

The area immediately surrounding the facility is characterized primarily by flat terrain with a mixture of land-use zoning including residential, mixed-use, and industrial. Existing land-use zoning information for the area surrounding the facility is discussed in Section 4.8. The topography of the area immediately surrounding the facility is presented in Figure 2-2.


PAGE 2

2.2 Process Description

The facility produces MDF from wood furnish purchased as residuals from other wood products facilities and sawmills in the surrounding area. The wood furnish, composed mainly of chips, sawdust, and planer shavings, are transported to the facility by truck and unloaded for on-site storage.

The wood furnish is processed in a pressurized digester and refiner system to produce wood fiber, referred to as a fiber stream. Resins are blended with the fiber stream in the pneumatic transfer line (blowline blending), as it is conveyed to two direct natural gas-fired flash tube dryers for drying. The dried fibers are then formed into mats. Each mat is cut and trimmed to size and then cured in the hot press to form panels. Steam for the drying- and pressing-related processes is supplied by a boiler that can be fueled by either sanderdust and/or natural gas. Particulate matter (PM) emissions generated by fuel combustion in the boiler are controlled by a baghouse.

After leaving the hot press, the cured panels are allowed to cool in a series of board coolers. Once cooling is complete, each MDF panel is sanded and cut to finished product dimensions. Emissions generated by the two flash tube dryers and the hot press are controlled by baghouses for control of PM, followed by a regenerative catalytic oxidizer (RCO) for control of organic TAC emissions. The facility also operates several other baghouses for controlling PM emissions from material handling processes, and for collecting wood residuals to be recycled back into the manufacturing process.

A process flow diagram outlining the MDF manufacturing process and points of emissions to atmosphere is presented in Figure 2-3.

3 EMISSION ESTIMATES AND MODEL SOURCES

Daily and annual TAC emission estimates for the process equipment and emissions control devices considered to be toxics emissions units (TEUs), as defined in OAR 340-245-0020(60), were prepared by RFP as shown in the DEQ-approved TAC emissions inventory. The DEQ-approved daily and annual TAC emission estimates will be converted to units of grams per second (g/s) for purposes of conducting the Level 3 Risk Assessment as shown in Table 3-1 and 3-2, respectively. Additional detail regarding the how the DEQ-approved daily and annual TAC emission rates will be used to complete the Level 3 Risk Assessment will be provided in the Risk Assessment Work Plan submittal.

The TEUs identified in the DEQ-approved TAC emissions inventory will be represented in the dispersion model developed to represent the facility. Each TEU included in the dispersion model will be modeled using a unit emission rate equivalent to 1 g/s for all modeled source types, except for area sources as shown in Table 3-3. Emission rates for area sources will be equivalent to 1 g/s divided by the corresponding area for that TEU, resulting in emission rates with units of g/s per square meter. Additional details describing unit emission rate modeling are provided in Section 4.4.

The specific procedures for assessing the risk of each TEU is dependent on the TEU designation per OAR 340-245-0050(4). As required by OAR 340-245-0020(5), RFP will segregate emissions from the


PAGE 3

combustion of natural gas into a distinct TEU (or TEUs) and separately determine risk at each exposure location from those TEUs. The specific TEU designations will be provided in the Risk Assessment Work Plan submittal. However, for purposes of air dispersion modeling and this modeling protocol, each TEU identified in the DEQ-approved TAC emissions inventory will be included in the dispersion model of the facility.

3.1 Boiler

The facility uses a boiler that can be fired on sanderdust and/or natural gas. The boiler has a maximum heat input capacity of 77 million British thermal units per hour (MMBtu/hr) when combusting both sanderdust and natural gas fuel, and a maximum heat input capacity of 90 MMBtu/hr while combusting only natural gas fuel. The boiler is capable of producing a total of 80 thousand pounds of steam per hour.

Exhaust from the boiler is routed to a multiclone for removal of coarse particulate, and then to a baghouse for control of fine PM and metal (i.e., TACs). The exhaust stack for the boiler will be represented in the air dispersion model as an individual point source with a unique label (BOILER). The proposed release parameters for the boiler stack are presented in Table 3-3.

3.2 RCO

The RCO is used primarily to control emissions generated by operation of the flash tube dryers and the MDF press. The RCO is fueled by a total of six natural gas-fired burners with a combined maximum heat input capacity of 24 MMBtu/hr. The burners provide the heat required to bring the RCO up to operational temperature, as well as the supplemental heat required to maintain the necessary RCO oxidation temperature. The natural gas required to sustain operating temperature of the unit is typically less than the heat input capacity of the burners.

Exhaust from the RCO natural gas-fired burners, flash tube dryers, and the MDF press will be represented in the dispersion model as a single point source with a unique label (RCO). The proposed release parameters for the RCO stack are presented in Table 3-3. Supporting details and descriptions for the flash tube dryer and MDF press are provided in the following subsections.

3.2.1 Flash Tube Dryers (Dryers 2 and 3)

The facility operates two flash tube dryers, identified as Dryers 2 and 3, to remove excess moisture in the wood fibers. Dryer 2 produces dried-face material (surface layers of panels) and Dryer 3 produces dried-core material (inner layer of panels). Dryers 2 and 3 are directly heated by natural gas-fired panel burners and/or indirectly heated by steam coils (using steam generated by the boiler). Indirect steam heat is maximized to the extent possible, depending on steam availability, with natural gas heat used primarily for supplemental purposes.

Exhaust from Dryers 2 and 3 is routed to one of six process baghouses operating in parallel for fiber recovery and precleaning prior to entering the RCO for final emissions control. It is important to note that, since the facility utilizes blowline blending, exhaust gases from the pressurized digesters, refiners,


PAGE 4

and application of the resins and waxes are incorporated into the flash tube dryer exhaust stream. Exhaust gases generated by natural gas-fired combustion from the direct-fired panel burners are also a part of the flash tube dryer exhaust stream and are routed to the RCO.

3.2.2 MDF Press

The MDF press is a steam-heated, multi-opening hot press housed in a partial enclosure to capture emissions. Pre-dried and blended mats are loaded into the hot press, which uses heat and pressure to cure the resin and produce MDF panels.

Exhaust gases captured by the partial enclosure are routed to one of three baghouses operating in parallel for fine PM removal, prior to combining with the flash tube dryer exhaust. The combined exhaust stream is then routed to the RCO for final emissions control.

3.3 MDF Press Fugitives

Uncaptured emissions from the MDF press (i.e., emissions not captured by the partial enclosure and routed to the RCO) are assumed to emit to atmosphere passively as fugitive emissions. The MDF press fugitive emissions will be represented in the dispersion model as a volume source with a unique label (PRESSFUG). The proposed release parameters for the volume source are presented in Table 3-3.

Roof vents and/or building openings are not located in close proximity to the press partial enclosure. As a result, MFA proposes to model the MDF press fugitives directly above the press partial enclosure area as a single volume source. The dimensions of the MDF press partial enclosure and adjacent building height will be used to define the volume source initial lateral dimension and initial vertical dimensions, respectively.

3.4 MDF Former

The MDF former represents the vacuum forming system that produces a mat from the blended and dried fiber. Four forming heads spread the blended and dried fibers on a vacuum belt to form a continuous mat. The mat is then pre-trimmed to rough size before it enters the hot press.

Emissions generated by each forming head are controlled by one of four baghouses identified in the existing permit under the material handling emission unit. Each baghouse will be represented in the dispersion model as a horizontally oriented point source with a unique label (FORM1BH, FORM2BH, FORM4BH, and FORM5BH). The proposed release parameters for each forming head baghouse stack are shown in Table 3-3.

3.5 MDF Board Cooler

MDF panels from the hot press enter the MDF board cooler, where they are moved through indexing wheels. Cooled air is circulated between the MDF panels, allowing them to cool prior to final stacking.


PAGE 5

Exhaust from the MDF board cooler is emitted to atmosphere through a series of roof vents (12 roof vents in total) located directly above the MDF board cooler. The exhaust vents are typically powered, but each vent can also be operated passively, depending on the desired product and ambient weather conditions. However, multiple vents are typically powered at all times the board cooler is in operation. Therefore, exhaust from the MDF board cooler will be represented in the dispersion model both as a point source and as two distinct volume sources.

The powered roof vents will be represented in the dispersion model as a representative individual point source with a unique label (BC1), while the group of passive roof vents will be divided into two distinct volume sources with unique labels (BC2 and BC3). The length of side for both volume sources will be set based on the general extents of adjacent roof vents. The proposed release parameters for each MDF board cooler release points are shown in Table 3-3. MFA assumes that the active ventilation provided by the powered vents will exhaust almost all the emissions generated by the MDF board cooler. To reflect this, 90% of the total emissions generated by the MDF board cooler will conservatively be assigned to the point source representation, and the remaining balance will be assigned evenly between the two volume sources.

3.6 MDF Sander

The MDF sander smooths the surface of the MDF panels to final product specifications as part of the finishing operation. PM emissions generated by the MDF sander are controlled by a baghouse.

Emissions from the MDF sander baghouse will be represented in the air dispersion model as an individual point source with a unique label (SANDBH). The proposed release parameters for the MDF sander baghouse stack are shown in Table 3-3.

3.7 MDF Finishing Saw and Board Trim Hog

The MDF finishing saw and board trim hog are also utilized in the finishing operation to cut MDF panels to the appropriate final product dimensions. Trimmed material from the MDF finishing saw passes through the board trim hog for particle size reduction, generating wood furnish. The hogged wood furnish is then recycled back into the MDF manufacturing process.

Emissions generated by operating the MDF finishing saw and board trim hog are controlled by a baghouse identified in the existing permit under the material handling emission unit. The MDF finishing saw and board trim hog baghouse stack will be represented in the air dispersion model as an individual point source with a unique label (SAWBH). The proposed release parameters for the MDF finishing saw and board trim hog baghouse stack are presented in Table 3-3.

3.8 Coatings

Coating products, which include spray paints and marking inks with varied TAC compositions, are used for marking MDF panels. The coating products are primarily used within the finished goods warehouse. Fugitive emissions produced from using each coating product (i.e., spraying and/or ink


PAGE 6

drying) are assumed to be uncontrolled and emitted through nearby vents spaced incrementally along the finished goods warehouse roof.

Fugitive emissions from coatings use will be represented in the air dispersion model as a volume source with unique label (COATINGS). The proposed release parameters for the volume source are shown in Table 3-3.

4 AIR DISPERSION MODELING METHODOLOGY

The following subsections detail the proposed conceptual site model for the facility. The proposed conceptual site model will be used in support of the Level 3 Risk Assessment.

4.1 Model Selection

MFA proposes to setup the dispersion model of the facility using the models shown in Table 4-1. Lakes Environmental, a third-party overlay software, will be used to execute the dispersion model.

4.2 Meteorological and Terrain Datasets

In preparation for air dispersion modeling, MFA obtained the meteorological and terrain data files shown in Table 4-2 below.

4.2.1 Surface Meteorological Data

Surface meteorological data were collected from the Rogue Valley International-Medford Airport monitoring station (ID 725970) located in Medford, Oregon (Medford met station). Hourly wind speed, wind direction, cloud cover, and temperature data for the years 2014 through 2018 were downloaded by file transfer protocol (FTP) from the National Center for Environmental Information (NCEI). The Medford met station was chosen as the most representative, publicly available surface meteorological data for the facility for the following reasons:

• The Medford met station represents the closest meteorological station to the facility location with data available for download from the NCEI. The Medford met station is approximately 4.1 kilometers to the northeast of the facility, and is located in an area characterized as flat with minimal terrain features.

• Both the Medford met station and the facility are centrally located within Rogue valley.

The Medford met station is part of the National Weather Service Automated Surface Observation Systems (ASOS) network. The Medford met station collects wind speed and wind direction, both of which are sampled once per second, with the average computed every five seconds. These data are referred to as “ASOS 1-minute.”

The Medford met station is part of the Ice-Free Winds Group (IFW) within the ASOS network. IFW stations collect wind data, using a sonic anemometer, which has no minimum detection threshold to determine “calms.” The ASOS 1-minute data (TD-6405) for the years 2014 through 2018 were extracted by FTP from the NCEI. These data were processed using the USEPA AERMINUTE program.

4.2.2 Upper Air Data

Upper air meteorological data were collected in the Forecast Systems Laboratory format for Medford, OR (station ID 24225), from the National Oceanic and Atmospheric Administration/Earth System Research Laboratory Radiosonde Database. Upper air meteorological data were extracted for the years 2014 through 2018.


PAGE 8

4.2.3 Data Processing―AERMET

The surface and upper air meteorological data were processed using the USEPA AERMET program to produce five years of model-ready meteorological data for use in the AERMOD dispersion model. The adjustment to the surface frictional velocity (ADJ_U*) option was selected as part of the AERMET processing. The land use surface characteristics were processed using AERSURFACE, and AERMINUTE was used to process and incorporate the ASOS 1-minute wind data into AERMET.

When ASOS 1-minute data are used, AERMET enables a default wind speed adjustment option. This option adds 0.26 meters per second (m/s) to all wind speeds to account for wind speed truncation (in units of whole knots) applied by the ASOS quality assurance system. Per the USEPA technical memorandum titled “Use of ASOS meteorological data in AERMOD dispersion modeling”1 dated March 8, 2013, a minimum wind speed detection threshold of 0.5 m/s was used to account for the adjustment. Wind direction randomization was not selected when running AERMET because ASOS 1-minute data increase the precision of wind direction measurements and, unlike non-ASOS data, are rounded to the nearest ten whole degrees.

After executing AERMET for each calendar year, the surface and profile files were combined to create a complete 5-year meteorological dataset for use in the dispersion model. An analysis of the data completeness for the proposed meteorological dataset was performed by MFA using the QA feature available in the Lakes Environmental software. As shown in Table 4-3, the surface and profile files produced by AERMET are more than 90% complete for each calendar quarter in the meteorological dataset.

A wind rose for the meteorological dataset described above is presented in Figure 4-1. The wind direction for this meteorological dataset is predominantly north to northwest, with a southerly component. Note this wind direction orientation is consistent with the orientation of the Rogue Valley.

4.3 Land Use

In preparation for air dispersion modeling, AERSURFACE was used to generate seasonal values for albedo, Bowen ratio, and surface roughness heights. The National Land Cover Dataset, 1992 (NLCD92) land cover class definitions for the State of Oregon were downloaded from the U.S. Geological Survey (USGS). These data were processed using the USEPA AERSURFACE land use tool to generate the surface characteristics necessary to run AERMET. MFA proposes to process AERSURFACE using the settings described in Table 4-4.

Surface moisture conditions were determined following the methodology set forth in the US EPA AERSURFACE User’s Guide dated January 16, 2013 (AERSURFACE User’s Guide). Section 2.2 of the AERSURFACE User’s Guide states “the surface moisture condition can be determined by comparing precipitation for the period of data to be processed to the 30-year climatological record, selecting “wet” conditions if

1 https://www3.epa.gov/ttn/scram/guidance/clarification/20130308_Met_Data_Clarification.pdf

https://www3.epa.gov/ttn/scram/guidance/clarification/20130308_Met_Data_Clarification.pdf


PAGE 9

precipitation is in the upper 30th-percentile, “dry” conditions if precipitation is in the lower 30th-percentile, and “average” conditions if precipitation is in the middle 40th-percentile.”

Annual precipitation data for each year of the 5-year meteorological dataset were reviewed and compared against the 30-year climatological record to determine the representative surface moisture condition for each modeling year. As shown in Table 4-5, the average annual precipitation varied between the lower 30th percentile to greater than the 70th percentile of the 30-year climatological record. To account for this variability, AERSURFACE was executed for each year using the corresponding surface moisture condition associated with that year’s annual rainfall.

MFA proposes to execute the dispersion model using rural dispersion coefficients. To make this determination, MFA followed the land use procedure, as recommended by USEPA “Guideline on Air Quality Models”2, to conclude that less than 50 percent of the land use within the modeling domain is represented by the urban land use type.

4.4 Unit Emission Rate

Results from the air dispersion model runs, executed using unit emission rates for each TEU identified in the DEQ-approved TAC emissions inventory, can be used to derive the predicted concentrations for multiple TACs from a given TEU. MFA proposes to execute the dispersion model using unit emission rates for all TEUs, for both the annual and daily (i.e., 24-hour) averaging periods, as shown in Table 3-3.

The maximum modeled unit concentration in micrograms per cubic meter (ug/m3) for each averaging period will be considered a modeled “dispersion factor” with units of ug/m3 per g/s. When multiplied by the TAC emission rate for the modeled TEU, the result is the modeled concentration of the TAC. The dispersion factors will be used to conduct the Level 3 Risk Assessment, in combination with TAC emission rates for each TEU in g/s and the risk-based concentrations (RBCs) in ug/m3 set forth under OAR 340-245-8040 Table 4.

4.5 Emissions Source Locations

The location of each TEU to be included in the dispersion model is shown in Figure 4-2.

4.6 Building Downwash

The most recent version of the USEPA Building Profile Input Program, incorporating the Plume Rise Model Enhancements Algorithms (e.g., BPIP-PRM), will be used to calculate direction-specific building downwash parameters for all significant building structures located at the facility. The current version of BPIP-PRM will be used as shown in Table 4-1.

2 Appendix W to Part 51 – “Guideline on Air Quality Models”. See Section 7.2.1.1(b).


PAGE 10

The proposed locations for structures that are projected to influence downwash are included in Figure 4-2. All stacks at the facility meet Good Engineering Practice design parameters. Table 4-6 presents a summary of the proposed building heights to be included in the air dispersion model.

4.7 Receptor Locations and Terrain

Dispersion factors will be determined for each modeling receptor identified outside the facility property boundary. MFA proposes to place modeling receptors at potential exposure locations in the surrounding area up to 10 kilometers away from the center of the facility. Figure 4-3 presents the proposed receptor spacing and locations for the modeling domain. Figure 4-4 presents the proposed receptor locations in the immediate area surrounding the facility.

Receptors will be defined in the dispersion model as shown in Table 4-7. If high impact areas are identified outside of the 50-meter grid upon review of modeled unit concentrations, MFA will place additional receptors in 25-meter space increments within applicable areas.

Table 4-7. Proposed Receptor Locations

Receptor Spacing Receptor Distance

25 m Along fence line and out to at least 200 m from fence line

50 m 600 to 1,000 m

100 m 1,000 to 2,000 m

200 m 2,000 to 3,000 m

500 m 3,000 to 10,000 m

MFA identified multiple locations considered to be “sensitive areas” (e.g., schools) within approximately 1-kilometer from the facility property boundary. Identified sensitive area are presented in Table 4-8. Each sensitive area shown in Table 4-8 will be accounted for in the dispersion model by a proposed receptor location.

(a horizontal resolution of roughly 10 meters) and processed using the current version of AERMAP as shown in Table 4-1.

4.8 Land-Use Zoning Classification Data for Determining Exposure Types

In anticipation of dispersion modeling, the Department of Land Conservation and Development’s statewide zoning data were reviewed to determine land-use classifications for areas within the modeling domain. The statewide zoning classifications provide the basis for the initial categorization of exposure classifications (e.g. residential, non-residential worker, non-residential child, or acute), as shown in Table 4-9. The zoning data was further evaluated against local data sets such as City of Medford zoning, Jackson County zoning and school-location information. MFA also reviewed aerial imagery via Esri AcrGIS and Google Earth software, and a physical site inspection of select areas was performed by RFP personnel to determine whether the existing zoning information reflects actual land-use and the corresponding exposure type categorization.

Figure 4-5 presents the existing land-use zoning identified for the modeling domain, and Figure 4-6 is provided for the area immediately surrounding the facility. Figures 4-7 and 4-8 present the corresponding exposure location categorization for the modeling domain and the immediate area surrounding the facility, respectively. For additional clarification, Table 4-10 shows all proposed receptor locations where the determined land-use and exposure location classifications differ from the statewide zoning information.

For purposes of this modeling protocol, RFP proposes the preliminary determination of exposure type to establish the receptor locations where ambient concentrations will be modeled. Final exposure determinations for use in the Level 3 Risk Assessment will be included in the Risk Assessment Work Plan submittal.

5 CLOSING

MFA looks forward to working with the DEQ throughout the CAO permit application process. If there are any questions or comments regarding this modeling protocol, please contact Brian Snuffer at (971) 254-8077.
